BROODER STOVE.

Application filed September 17, 1921i. Serial No. 738,176.

This invention relates to a broeder stove and its object is te provide means whereby a broeder house tor young chickens may be heated to the correct temperature and rnaintained at that temperature until the chicks do not require artificial. heat.

lt will be understood by those skilled in the art that it is necessary to maintain a broeder house at a unitorin temperature by seine kind et an apparatus Which will give the eitlect et a hen hovering her chic rs, because it is natural for thern to crowd tegether when night ceines' and it the heat is not properly diliused they will crowd up so closely as t-e lrill the weaker chicks.

ln addition to the danger el killing the weaker chicks, there is danger ot sweating all et thein it they crowd teo closely. Such considerations as the above are of no par* ticular moment Where sinall numbers et ehiclrs are raised, but Where as inany as 1800 chicks are raised, in one roorn, as With one et these stoves it Will be seen that it is necessary to have alinost perfectly natural conditions to raise a large percentage ot the chicks.

Another object et the invention is to provide ineans whereby the broeder stove may be reinoved and a cover placed over the burner when artificial heat is no longer necessary.

lt will be understood that any suitable type et burner or 'uel may be used to accomplish the saine results.

Other objects et the invention will appear as the description proceeds.

in embodiment of the invention is shown in the accompanying drawings in Which the saine reference numeral is applied te the saine portion tl'iroughout, but l ain aware that there may be inodiiications thereof.

Fig. l is a vertical sectional view tl'lroupgh the broeder stove and the floor of' the broeder house,

Fig. 2 is a sectional view on a large. scale et the corner oit the burner drum,

Fig. 3 is a view in side elevation of the stove and door of the broeder house showing the Way the chicks collect around the stove when they go to sleep, and

Fig. 4 is a plan view ot the steve, the dotted circles indicating' the area in which the chicks collect When about 1800 are in eluded in one batch.

The broeder house is ordinarily in such installations as the present about twelve to tourt-een feet square and is made With Well insulated tight Walls to retain as inuch heat as possible. y

The broeder lioor indica-ted at l, is supported by the jeists 2, a hele being provided in the center el the rooin for the stove. The hole is circular and is provided with two channel iron supports 3 and which are secured to the floor by bolts 5. y

Qn these two beams the burner pan 6 is placed, said pan having its lower corner beaded at i" and having a central opening to receive the draft tube 8. The draft tube 8 has pan 9 riveted thereto by brackets l0, the object being to prevent pulses ot' air trein blowing1 the liaine out accidentally.

There is a hole in the burner drinn bottoin thro'oeh which the gas pipe ll is installed, said pipe having a plurality ot' burner tips l2.

rl`he supply valve ll and the tl'ierinostat l/i are both installed in the broooer rooni, the valve tor convenience in operation and the thermostat for the purpose et rognlating` the roein temperature by decreasing` or increasing the fuel supply.

lnside the burner drinn 6 there is a ring l5 et asbestos or other tire-prooiC insulating libre which is held in place by a ring` 1G.

Slidable over the ring il is the cylindrical heater drinn 1'1" the fiat ringl l@ secured to the floor lillingr up the space between the floor and said drnin.

The hover consists ot a ilat circular sheet. pendingarl central litly over the 'top o the drinn l.. Secured to the outer edo, i' oi the sheet i8 is a flat cone il() which lies an outlet pipe 2l connected te the chirunev 09.

lllithin the cene and at a distance 'i several inches troni the bottoni '5.8" there is a 'fiat sheet 23, rivets at its outer edges being; used to lsecure it to the cone and it has 'notches 24e cut in it to allor: the eases 'trein the burner to pass to the chiinney. i

A short pipe 25 is secured in the cone and under the plate 23 to atlerd hand hole to light the burner when desired, a. tight cover 25 being' provided to prevent the escape ot into the rooin.

rllhe cone also has tvvo rines S37, secured thereto to provide ineens to raise it out et" the Way when it is not in use.

l l l) t will be seen that the ring 17 iiiictionally engages the ring;I 6, und 19 frictionelly engages the drum 17 so when the chicks do not require artieial heet the cone is raised to the root to be out ot the way of cleaning the house, the drinn 1T is removed and the burner is covered over.

In operation the burner is started by lighting it through the hand hole extending` through the Cone and the thermostat then operates to keep the rooin et the required temperature. Since the hot ges escaping is only that due to ythe combustion or' the `liu-el, the hee/ter is very economical, und as it spreads the heut uniformly over a wide eren the ehiels go to sleep in a large ring as indicated in Figs. 3 und f1, spread out enough to prevent injury to the weaker ones.

Such heaters as this are from four to tive feet in dia-meter and they serve to heat L rooin for about 1800 chicks.

Vhat I claim is as follows, but inodiiicetions may be made in carrying out the invention shown in the drawings and in the above particularly described forni thereof within the purview of theinvention ys delined by the annexed claim:

1n a broeder stove, u` burner, a pun having un open bottoni within which the burner is installed, e thermostat to regulate the supply oi fuel to the burner, an insulating materiel around the edge of the burner pun, @heater druin detaehably connected to seid pun, u closed liet cone mounted upon the heater drum, u partition within the cone to cause the uniform distribution of heat tl'iereirom1r a pipe for the escape of burned ges and u hand-hole pipe extending through the cene und partition therein to permit the burner to be lighted.

1n testimony whereof have hereunto set my hand this 12th day of September A.
